METHOD OF FEJIAKING LAGING TIPS.

Application filed June 6,

T 0 all whom it may concern:

Be it known that I, Faun E. Bunrrncarrn, a citizen of the United States, residing at Pawtuclret, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Methods of Making Lacing Tips, of which the following is a specification.

This invention relates to an improved method of forming a lacing tip, and has for its object to form a lacing tip with a stifiening, metal core and wrapping the lacing material around the core, the same being firmly held in wrapped position by cement.

My invention further consists in the provision of a stiffening core which may be made of a length of soft wire or the like and to roughen the surface of this core so as to cause the material of the lacing to cling to the core when folded about it to prevent the fabric from becoming released from the core and preventing the core from working out through the end of the tip.

Vlith these and other objects in View the invention consists of a new and novel method of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a perspective view showing a lacing with my improved tip formed on the ends thereof.

Figure 2 is a side elevation partly in section illustrating the method of feeding the wire core, of severing the same, and depositing the severed sections onto the lacing.

Figure 3 is a sectional end view of a lacing showing the folded members for wrapping the fabric about the core, also showing the ring or tube for previously bending the fabric into crescent shape.

Figure 4 is a top view illustrating a length of stiffening core as deposited on the fabric before the latter is folded over the core.

Figure'5 shows the double length of tip, a section of the fabric being folded about the core and secured thereto by cement.

Figure 6 is a sectional end view showing the fabric as folded about the core with its edges abutting.

Figure 7 is an elevation illustrating a 1924. Serial NO. 718,234.

sectional end view of the lacing in curved form and showing a flaring ceine11t-depos1ting nozzle whlch is adapted to deposit the cement completely across the width of the lacing fabric so that its edges will remain in position when the cement dries.

It is found in practice of advantage to stiffen the tip of a lacing by wrapping the body of the lacing about a metal core, which core is preferably formed of soft wire that may be cut and fed in the desired lengths to the fabric after the latter has been treated with a cement along the tip-forming portion, and the fabric thus treated may be folded automatically about the metal core and subsequently severed at its middle to provide tips of the required length on the adjacent ends of the lacings. It is also found of advantage to roughen the surface of the core so as to cause the fabric to adhere more closely to the core and to positively prevent the metal from working out at the end of the tip after the same has been severed; and the following is a detailed description of one construction and method of forming a tip by which these advantageous results are accomplished With reference to the drawings 10 designates a lacing fabric which may be of any suitable length and of any suitable material and of any desired width.

In forming a tip by my improved method and construction, I first roll or bend the side edges of the strip of lacing fabric into substantially crescent shape in cross section, as best illustrated in Figures 2 and 3, by drawing the fabric through rings or tubes 12 and 13, and while in that form or position a suitable section or length of the fabric is treated to cement which is forced from the receptacle 14 by means (not shown) onto the fabric as it is drawn through the tube 12. This cement treated section of fabric is now arrested in its feeding at a point 15 beneath the magazine or chute 16 from which magazine or chute a length of wire 17 is deposited onto the curved portion of the lacing after having been fed forward by the knurled or corrugated feeding rolls 18 and severed. by the cooperating cutting blades 19 and 20.

After the severed length of wire has been deposited onto the curve and cement-treated section of the lacing fabric, folding jaws or dies 21 are advanced from opposite sides and are caused to Wrap the fabric about the core into the shape illustrated in Figures 5 and 6, and these dies 21 after having performed the folding operation are caused. to hold the fabric in wrapped position until the cement becomes set after which these jaws are withdrawn releasing the finished tip. Between these dies 21 is a cutter plate which cooperates with the dies to also sever the tip in halves so that upon being released by the dies the lacing is finished to be withdrawn.

In some instances, it is found of advantage to roughen the surface of the core by raising spurs on its surface or otherwise roughening the surface of the Wire by ac tion of the feeding rolls 18 upon it.

It is found that when a surface is so roughened the fabric clings more closely to the core and also effectually prevents the core from working endways beyond the end of the tip after it has been cemented therein.

My improved stiffening tip is very handsome and attractive in appearance inasmuch as the fabric itself forms an outer surface of the tip and does not have to be colored or otherwise treated to correspond to the color of the body portion of the lacing.

Having thus described one illustrative embodiment of my invention and the best mode known to me for carrying out my method, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for the purpose of limitation, the scope of the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A new method of making a lacing tip, which consists in applying cement to a sec tion of the lacing material, depositing a stiffening core member upon the cement treated portion and folding that portion about the core.

2. A new method of making a lacing tip,

which consists in applying cement to a short section of the lacing fabric, depositing a short stiffening core member upon the cement-treated portion, folding said treated portion about the core automatically, and retaining the fabric in such folded position until the cement is set.

3. A new method of making a lacing tip, which. consists in folding a portion of the strip of lacing fabric into substantially crescent shape in cross section, applying cement to the shaped section, depositing a stiffening core on the cemented portion, and wrapping or folding that portion about the core.

a. A new method of making a lacing tip, which consists in applying cement to a short section of lacing fabric, roughening and depositing a short length of wire onto the cemented portion of the fabric, and folding the cement-treated portion of the fabric about the roughened core.

5. A new method of making a lacing tip, wh'ch consists in applying cement to a short section of lacing fabric, roughening and depositing a short length of wire onto the cemented portion of the fabric, and folding the cement-treated portion of the fabric about the roughened core and holding the fabric in folded position until the cement has set.

In testimony whereof I affix my signature.
